It’s a delicate balance: You want your glass of whiskey to be icy, but you don’t want it to be watered down. These stainless steel cubes solve the problem: Just pop them into the freezer, wait until they’re frosty to the touch, and use them to cool down your cocktail (or your lemonade) without diluting it. (We’ll drink to that!) Each set comes with 4 cubes.
